Testing theories of large scale structure formation and growth using galaxy surveys
(The University of Edinburgh, 2021-07-31)The distribution of galaxies in the Universe is not random: rather, galaxies cluster in a structured way. The formation and growth of these large-scale structures (LSS) provides powerful dynamical probes for cosmology. ... -
Towards a new generation of Parton Distribution Functions: from high-precision collider data to lattice Quantum Chromodynamics
(The University of Edinburgh, 2021-11-27)A precise understanding of the proton structure, encoded in Parton Distribution Functions (PDFs), is required to make reliable predictions and analyses at the Large Hadron Collider (LHC), the main source of experimental ... -
Fracture mechanics of bacterial colonies growing in soft gels
(The University of Edinburgh, 2021-07-31)When submerged in agarose gels, growing Escherichia coli (E. coli) form lenticular colonies. In this thesis I first present a study on the origin of this morphology. Using single plane illumination microscopy, I record ... -
Computational rheology of liquid crystalline composite and active materials
(The University of Edinburgh, 2021-07-31)Liquid crystals are a type of soft matter that exists as a mesophase between the solid and liquid phase. As a result, they are observed to exhibit some properties which are characteristic of each of these phases. For ... -
Low dimensional models of the transition to turbulence
(The University of Edinburgh, 2021-07-31)The transition from a regularly ordered state of fluid motion to chaotic and turbulent regime has been long observed and progressively understood through the discovery and application of theoretical tools and frameworks. ... -
Formation, structure and mechanical properties of hydrogel-emulsions
(The University of Edinburgh, 2021-07-31)Oil-in-water emulsions are ubiquitous in fields such as food, cosmetic and pharmaceutical industries due to their ability to impart texture, or transport or solubilise hydrophobic constituents in a water continuous phase. ... -
Phase transformation and transport in sulphur at high pressure and temperature.
(The University of Edinburgh, 2021-07-31)Sulphur has one of the most complex high pressure-temperature phase diagrams of the elements, with many solid phases and multiple liquid phases reported up to 40 GPa (400 kbar). The high temperature stability of solid ... -
Investigation of the bacterial mechanosensitive ion channel of large conductance within bacterial membrane mimetics in response to simple antimicrobial molecules
(The University of Edinburgh, 2021-07-31)This thesis describes the use of neutron and X-ray scattering and reflectivity to characterize the structure of the Mechanosensitive Ion Channel of Large Conductance, MscL, within bilayer constructs. MscL is known to ... -
B meson decays, conformal anomalies and gauge invariance
(The University of Edinburgh, 2021-07-31)In this thesis, we discuss the calculation of conformal anomalies using curved spacetime and heat-kernel techniques, and QED corrections to semi-leptonic decays of the pseudoscalar B meson at the full differential level. ... -
Computer simulations of biofilm spatial structure
(The University of Edinburgh, 2020-11-30)Surface attached communities of bacteria, known as biofilms, can grow in a variety of morphological forms. Classifying these distinct spatial structures is important for understanding the link between the spatial structure ... -
Prospects for precision measurements of the Top-Yukawa Coupling and CP Violation in ttH Production at the CLIC e+e− Collider
(The University of Edinburgh, 2021-07-31)High energy particle colliders provide unique facilities to investigate the physics that take place at the smallest scales. The thesis present works for both future and upgraded colliders. CLIC - the Compact Linear ... -
Measurement of the ⁷²Ge(n,γ) cross section at n_TOF CERN over a wide energy range and Implications for stellar Nucleosynthesis

On-shell physics of black holes
(The University of Edinburgh, 2021-07-31)On-shell methods are a key component of the modern amplitudes programme. By utilising the power of generalised unitarity cuts, and focusing on gauge invariant quantities, enormous progress has been made in the calculation ... -
Effect of attractive forces on active-passive interactions

Non-standard neutrino interaction analysis with atmospheric neutrino data in Super-Kamiokande I-IV and the design of the Hyper-Kamiokande outer detector
(The University of Edinburgh, 2020-11-30)Neutrino oscillation is a well-established phenomenon and oscillation parameters are being measured with great accuracy. This unprecedented accuracy allows sensitivity to sub dominant effects which could indicate new ... -
Neutron scattering studies of hydrogenated molecular materials
(The University of Edinburgh, 2021-07-31)This thesis employs three neutron scattering techniques; neutron diffraction, inelastic neutron scattering, and quasielastic neutron scattering; to probe the properties of hydrogenous systems. These results are complemented ... -
Modelling cosmological structure formation in the non-linear regime
(The University of Edinburgh, 2021-07-31)We are entering an age of precision cosmology with upcoming instruments and surveys such as Euclid, the Dark Energy Spectroscopic Instrument (DESI), the Large Synoptic Survey Telescope (LSST) or the Rubin Observatory and ... -
MIST: a portable and efficient toolkit for molecular dynamics integration algorithm development
(The University of Edinburgh, 2021-07-31)The main contribution of this thesis is MIST, the Molecular Integration Simula- tion Toolkit, a lightweight and efficient software library written in C++ which provides an abstract interface to common Molecular Dynamics ... -
Colloidal particles at a liquid-liquid interface: interactions and rheology
(The University of Edinburgh, 2021-07-31)Colloidal particles at fluid interfaces are present in many industries and applications, including the food, pharmaceutical and cosmetics industries. Much work has focussed on the behaviour of charge stabilised colloidal ... -
New residual distribution hydrodynamics solver for galaxy formation simulations
(The University of Edinburgh, 2021-07-31)Numerical simulations are key to our understanding the complex physical processes present in the formation and evolution of galaxies. The vast majority of the baryonic component is in a gaseous state, modelled by solving ...
